Hi folks, this site has been a tremendous help for me in dealing with my B12, deficiency.
I prepare my B12 ampoules (I use 1ml syringe) 8-10 at a time to save time, I store the syringes at room temperature in a dark area. I inject 1ml EOD.
PLEASE ADVISE, Does anyone prepare syringes ahead of time for EOD, or daily use, with any negative effects?
Thanking you all in advance for your help.
No.It's really best to prepare then Inject.
Once the ampoule has been snapped its been exposed to the atmosphere.
A nurse will sometimes draw it up before you enter the room.
Most don't.
I personally would not prepare alot at one time .
Done actually see how it saves time .
The same time to prepare one .
Never heard before of anyone thinking to do this 🤔
My husband has r injections a day of insulin .
In a pen a pen it does stay sterile.
Before pens. Drawn up every time.
Nevef in advance.
He made time
Once again Thank you Nackapan for your help and advice.
I do mine as and when I need them I never do them in advance.
As Nackerpan has said once the ampouls have been broken they have been exposed to pollutants but then saying that doing so doesn't seem to have done you any harm. If it were me I would prepare as I use them just to be safe.
My doctor advised me to fill multiple syringes at once. I fill 8 x 0.25ml from a 2ml syringe and store them in the fridge as per doctor's advice. I inject every day so they are there 8 days.
Hi, Please don't take offence, but as a former nurse I'm shocked a doctor advised that ! Huge risk of bacterial contamination, plus the B12 potentially losing its efficacy.
As others are saying, Injections should ideally be drawn up at time of use, and up to eight days is way too long .
Please reconsider your injection schedule, thanks.
Best wishes x
The shorter time between drawing up and injecting the better.
The ampoules are sterile, the syringes aren't once they are out of their packets.
You risk introducing bacteria and other pathogens from the air, which can then multiply inside the syringe - and the longer it is before you use it, the more they can multiply, potentially doubling in number every 20 minutes or so.
It really doesn't take so long, in the grand scheme of things, to prepare fresh doses each time - and is nothing compared to the time you will lose if you get sepsis!
Keep safe!
I agree with most replys that it is better for you and the B12 to prepare as you use it. I used to get pharmacy compounded methylcobalimin, 30 syringes at a time and keep them in the fridge, but in my experience, the end of the month injections did not seem to have the same potency, as I had crashes more frequently. Also, as a suggestion, if you are taking a full 1ml injection of 1000 mcg B12, I suggest using a 2 or 3 ml syringe. It is recommended that syringes not be filled over 75% of capacity if possible. The larger syringe will be easier to handle and the risk of pulling the plunger out, or having it break during injection is lessened.
Has anyone had insomnia from B12 injections?
